Split Large PDF: what you need to know
Large PDFs are hard to email or upload, and long documents are easier to review in parts. This page starts in Every N pages mode: choose how many pages each part should have and FilesForU creates the files in order.
Splitting doesn't change the content or quality of any page — each part is an exact slice of the original.

Questions & answers
Can I split by file size instead of pages?
Splitting works by page count. Use fewer pages per part for smaller files, or compress the PDF first.
Will the pages lose quality?
No. Pages are copied exactly as they are.
Is there a page limit?
No fixed limit — very large files depend on your device's memory.
Are my files uploaded to your server?
No. This tool runs entirely inside your browser, so your files stay on your device. FilesForU never receives, stores or sees them.
Is it really free?
Yes. Every tool is free with a free account — no daily limit, no watermarks, and files up to 500 MB.
